 * NidoSpa Portfolio — Frontend stylesheet
 *
 * Estetica: editoriale sobria. Le foto sono protagoniste, la tipografia è
 * di servizio. Niente effetti che distraggano dal contenuto fotografico.
 *
 * Le custom property permettono override dal tema senza dover toccare il plugin:
 *   :root {
 *     --nidospa-pf-accent: #c8a04a;
 *     --nidospa-pf-label-bg: rgba(0,0,0,.85);
